Jillian’s Spinning: Keeping Track with Tags

I am newly in love with these big honking tags:

Shipping tags are my new friend

They are about 4″x 2″ and manilla folder thick. I’ve seen other people use them, but never have myself until recently.  I realized I can fit a whole lot of yarn info and yarn on a single tag.

Behold:

So much information

Here’s what I have listed on it so far: Fiber info, WPI single / finished yarn, YPP, TPI for plied yarn finished/unfinished, my wheel and her settings. The yarns on the tag are singles (I plan on making this spot an inch next time), a ply back sample and two plied samples unfinished and finished.

This is just a first pass as I’m working on a project. There is so much space for so many statistics!

How do you keep track of spinning and yarn information for a project and where do you keep it?
